Understanding Your ATU

Before we discuss the maintenance tips, let’s explain what an ATU is and how it works. An ATU is a cutting-edge wastewater treatment system that utilizes oxygen and aerobic bacteria to break down organic matter and remove contaminants from household wastewater. It consists of a treatment tank, an aeration chamber, and a clarifier, and it requires a reliable source of electricity to operate.

How to Maintain Your ATU

Here are some maintenance tips to remember if you want your aerobic treatment unit to work for years to come.

Regular Inspection

Schedule a professional inspection at least once a year or as the manufacturer recommends. During the review, our technician here at Country Side Sewer will meticulously examine for signs of wear and tear, such as leaks, broken components, or damaged electrical wiring. We will also meticulously verify that the aeration system is functioning optimally and that the lines have no blockages.

Proper Use of Water and Chemicals

The volume and quality of wastewater that enters your ATU can significantly impact its performance. It would help if you were mindful of water and chemicals used to prevent clogs and damage to the system. Avoid flushing non-biodegradable items, grease, and chemicals like paint, pesticides, and harsh cleaners. They can disrupt the delicate balance of bacteria in your ATU.

Pump Regularly

The treatment tank of your ATU requires regular pumping to remove accumulated sludge and scum. The pumping frequency depends on the size of your tank and the number of occupants in your household, but it typically ranges from 3 to 5 years.

Proper Aeration

Aeration is vital in ATUs, providing oxygen to the bacteria that break down organic matter. Ensure the aeration system functions optimally and the airlines have no blockages. Clean the diffusers or aerators as the manufacturer recommends to prevent clogging and ensure an uninterrupted oxygen supply.

Protect Your System 

Avoid planting trees or plants with deep roots near the system, as they can infiltrate the treatment tank and damage the pipes. Keep heavy equipment and vehicles off the ATU area to prevent soil compaction, which can hinder proper drainage and disrupt the system’s delicate balance.

Power Supply

ATUs require a constant and reliable power supply to operate. Keep the power flowing by ensuring that the electrical components, such as pumps, alarms, and blowers, are connected to a stable power source and have power backup in case of an outage. Regularly check the electrical connections for any signs of damage or corrosion, and replace them promptly.

In summary, properly caring for your ATU is no longer a mystery. By following our expert tips, you can effectively manage your ATU
